Arnold "Arnie" Mausser (born February 28, 1954) is an American former soccer goalkeeper who played with eight different NASL teams from 1975 to 1984.
Growing up in Queens, New York, with two younger brothers, Mausser played numerous sports, his favorite being basketball.
As Mausser got older, he trained with numerous local teams, eventually catching the eye of the coach of the Rhode Island Oceaneers of the American Soccer League (ASL).
Outdoors in 1976, his excellent play with the Rowdies (six shutouts and 28 goals scored against him in 24 games) led to his selection as a first team NASL All Star and the North American player of the year.
When the NASL folded, he briefly played with the Kansas City Comets of the Major Indoor Soccer League (MISL).
The ball flopped to the feet of Evaristo Coronado who easily scored the goal which eliminated the U.S. from World Cup contention and sent Costa Rica to the second round instead.
Mausser played one more game for the national team, a 5–0 thrashing by England on June 16, when he saved a penalty by Glenn Hoddle.
There is some debate as to Mausser not being selected to the 1990 World Cup squad which was likely because the team was looking at its youth rather than veteran leadership at the time.
